Long-term habitat changes in a protected area: Implications for herpetofauna habitat management and restoration

Long-term habitat changes in a protected area: Implications for herpetofauna habitat management and restoration

Point Pelee National Park, located at the southern-most tip of Canada's mainland, historically supported a large number of herpetofauna species; however, despite nearly a century of protection, six snake and five amphibian species have disappeared, and remaining species-at-risk populations are thought to be in decline. We hypothesized that long-term changes in availability and distribution of c...

Predicting Spatial Habitat Changes of Haftad-Gholleh Protected Area in Markazi Province, Iran

Haftad-Gholleh Area has recently encountered many changes. In this study, by using landsat images of the years 1996 and 2016, landuse maps were classified into four classes including: agriculture, rangeland, residential areas, and rocks. Land Change Modeler (LCM) and Habitat and Biodiversity Modeler (HBM) modules in the Idrisi GIS software were used to analyze the land use changes and habitat e...

Implications of Habitat Choice for Protected Polymorphisms

In this paper we reexamine how heterogeneous environments can enable protected polymorphisms. Building on the classical models by Levene and Dempster of dispersal and selection in two habitats, we systematically investigate how the maintenance of polymorphisms is affected by (i) local versus global density regulation and (ii) constant versus variable output from habitats to the next generation....

Long-term studies reveal the conservation potential for integrating habitat restoration and animal nutrition

Phenotype management: a new approach to habitat restoration

The goal of habitat restoration is to provide environmental conditions that promote the maintenance and growth of target populations. But rarely is it considered how the allocation of resources influences the diversity of phenotypes in these populations. Here we present a framework for considering how habitat restoration can shape the development and expression of phenotypes. We call this appro...
